Set system to go into suspend (s3), which functions correctly. Upon re-opening the lid it freezes at a black screen (no image, no backlight, no response from key combinations, though the led lights on the keyboard work). when attempting to run suspend in s1 after altering acpi-support (not exactly sure what the difference is supposed to be, just that there is one), it goes to a password prompt with a fair amount of hard drive activity (comparable, if not the same as normal when I'm not doing anything). Upon resume (from "s1" - not sure if i get there) everything works fine, but there is a small notification box in the lower right hand corner (a bit off screen, unfortunately), saying that the entry into suspend has failed. The failure of s3 is my main problem though, and the only thing keeping me from a total switch from windows.
Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?
